Pet's info: Dog | Lhasa Apso | Male | neutered | 12 years and 8 months old | 25 lbs
My dog has had this bump on his back for about a month now and he has a similar one on the top of his head for even longer. They don’t seem to bother him but they randomly start bleeding all the time. Should I put neosporin on them or does it need to be looked at by a vet? He’s almost 13 years old. First picture is his back. The second is his head.

Hi there. From what I can see in the photo, these bumps look consistent with a type of tumor called a sebaceous adenoma, which is a benign skin growth that is common in older small breed dogs. Sebaceous adenomas are harmless, and do not normally require any kind of treatment unless they are particularly large or located in an area where they're constantly being bumped and causing bleeding or drainage. In that case, they can normally be surgically removed without much difficulty. To be safe, I would recommend having them checked by your veterinarian in person, since it's not possible for us to make a definitive diagnosis from a photo. :)
